Try booting with ACPI disabled.

You can do this by appending acpi=off to the grub bootline entry starting with kernel.

what happens if you shutdown from the terminal i.e. the command "shutdown -h now" or "halt".

when i use the command "shutdown -h now" or "halt" it seems like its going to shut down but it starts right back up again
